Description

Technical Field

[0001] The utility model relates to the technical field of diaphragms, in particular to a winding device for electrolytic water hydrogen production diaphragms. Background Art

[0002] The diaphragm for electrolytic water hydrogen production is usually made of specific electrolyte materials. Its main function is to separate the hydrogen and oxygen generated by the decomposition of water during the electrolysis process and prevent them from mixing again. Common diaphragm materials include proton exchange membranes and alkaline diaphragms. These diaphragms play a key role in the process of electrolytic water hydrogen production, ensuring that the generated hydrogen and oxygen can be collected separately, thereby improving the electrolysis efficiency and safety. The diaphragm for electrolytic water hydrogen production usually needs to be wound or stacked and installed in the electrolytic cell. The purpose of this is to ensure that the electrolyte material can effectively isolate hydrogen and oxygen during the electrolysis process, and at the same time enable the electrolysis reaction to proceed smoothly.
